Goglio | June 23, 1998 |
A process for packaging coffee, which includes a grinding phase of the coffee coming from silos, a forming phase for forming flexible or semi-rigid containers and a phase for filling such containers with the coffee and subsequent sealing of the pack, in which, during the container forming phase, the containers are preliminarily filled with gas and, at the same time, closed at their top, in such a way as to be able to be opened again immediately before filling. The filling takes place in an atmosphere controlled by a flow of gas, wherein the gas for preliminarily filling the containers and/or for controlling the atmosphere during the container filling phase is drawn from a coffee grinding plant. An installation for putting such process into effect is also proofed.
